[Healeys] Torque settings for 100 engine

[Alan Seigrist]

Tadek -

The values you've listed are typically for the 6 cyl motor.

Head nuts for the 100 are 65 ft-lbs
Big end caps (piston rods) are 50 ft-lbs
Main Beaing Caps 75 ft lbs.

Everything else I'd run 40 ft lbs, manifold nuts excepted at 25 ft lbs
(to keep from pinching the gaskets which will cause vacuum leaks).
